Senior Software Engineer — CloudKit Client

DESCRIPTION

Apple is seeking an experienced Software Engineer to help build the next generation of cloud services infrastructure. You'll design and implement key components of the iCloud platform, integrating powerful new capabilities deep into the core of Apple's operating systems. Your work will enable entirely new applications and help scale existing ones—including iCloud Drive, Photos, Notes, Face Time, and many more. This is an opportunity to make a significant impact.
You'll collaborate with highly skilled teams dedicated to engineering excellence and deliver features that uphold strong privacy guarantees for our users.

Our team builds the on-device software that makes iCloud work. In this role, you'll focus on building Cloud Kit — Our privacy-focused sync and storage system. Cloud Kit manages user data for most Apple apps, as well as many third-party apps. You'll design and build the frameworks and daemons that support both systems, working closely with engineering teams across the company who are adopting this technology—and with colleagues who build our client and server dependencies.

A strong candidate will have experience and interest in Apple platforms, ready to tackle challenges like protocol design, interprocess communication, device resource management, API design, reliability, and performance. Since so much of the user experience depends on services, we're also looking for engineers who are passionate about complex distributed systems. We value thoughtful engineering, collaborative problem-solving, and shipping work we're proud of.

You'll have opportunities to deepen your expertise in distributed systems, security, and platform engineering.
